Description

Technical Field

[0001] This application relates to the field of LED lights, and in particular to an LED light with an ambient temperature control system. Background Technology

[0002] With the advancement of technology, especially the development of light-emitting diode (LED) lighting technology, indoor planting or plant factories have become possible. LED lights have high luminous efficacy and are gradually replacing traditional lamps, becoming the mainstay of plant lighting.

[0003] The ambient temperature for plant growth in the factory needs to be set to the optimal growth temperature. This requires controlling the ambient temperature. However, LED lights generate a lot of heat when providing light to the plants. This heat affects the ambient temperature for plant growth and also affects the lifespan of the LED lights themselves. Therefore, it is necessary to control both the ambient temperature and the LED light temperature in the factory.

[0004] In existing plant factories, LED lights are typically cooled by installing heat sinks or liquid cooling modules behind the LED light panels. Figure 1 A structural diagram of an LED lamp with a heat sink is provided for the prior art, such as... Figure 1 As shown, for the method of installing heat sink 1 after LED lamp 2, no liquid cooling module is used to cool the LED lamp. However, the heat dissipation efficiency of the liquid cooling module is much greater than that of heat sink 1. Therefore, the heat dissipation efficiency is low when the LED lamp is cooled by heat sink 1 alone. Figure 2 A structural diagram of an LED light equipped with a liquid cooling module is provided for the prior art, such as... Figure 2 As shown, for LED lights equipped with liquid cooling module 3, the heat dissipation efficiency is very high, but it cannot control the ambient temperature for plant growth. Other equipment, such as air conditioning, is still needed to control the ambient temperature, which increases the cost of the plant factory.

[0005] Therefore, how to design an LED light with an ambient temperature control system that can control the temperature of the LED light through a liquid cooling module, ensuring efficient heat dissipation of the LED light, while also controlling the temperature of the plant growth environment and reducing factory input costs is a problem that urgently needs to be solved by those skilled in the art.

Detailed Implementation

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0046] The core of this application is to provide an LED light with an ambient temperature regulation system to solve the problem that when a liquid cooling device for controlling the temperature of LED lights is installed in a plant factory, other equipment is still needed to control the ambient temperature, which increases the investment cost of the plant factory.

[0047] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] This embodiment provides an LED light with an ambient temperature control system, primarily used in plant factories to provide light for plant growth and control the ambient temperature while simultaneously controlling the LED light's temperature. Figure 3 and Figure 4 and Figure 5 The diagram shows a structure of an LED lamp with an ambient temperature control system. The LED lamp includes an LED lamp module 6, an ambient temperature control system 5, and an LED lamp driver 4. The ambient temperature control system 5 includes an inlet 7, an outlet 8, a water channel 9, and a heat exchanger 10. One end of the water channel 9 is connected to the inlet 7, and the other end of the water channel 9 is connected to the outlet 8. The water channels 9 are spaced apart and interconnected.

[0049] The model and quantity of LED light module 6 are not limited in this embodiment and can be selected according to the needs of the factory. The LED light module 6 can be set as a single layer or multiple layers according to the placement of the plants. The LED light strips in the LED light module 6 can be set at intervals or as a whole, which is not limited here.

[0050] The positions of the inlet 7 and outlet 8 of the ambient temperature control system 5 are shown in the diagram only to illustrate a possible relationship; their positions are not specified. The shapes of the inlet 7 and outlet 8 should match the connecting pipes between the water channels 9 and the external system, such as being circular, to prevent leaks. The water channels 9 are spaced apart but interconnected, allowing water to circulate freely. The water channels 9 can be laid along the brackets of the LED light modules 6 or arranged in a specific pattern; no limitation is made here. A greater number of water channels 9 will improve the temperature control effect on the environment and LED lights; however, too many channels will increase manufacturing costs. Therefore, the number of channels should be set according to the manufacturer's requirements or preset. The ambient temperature control system 5 needs to be connected to a temperature control system. This temperature control system, typically located outdoors, can be a water tower or a compressor, and the water it draws can be well water, river water, etc.; no limitation is made here.

[0051] The heat exchanger 10 only needs to be installed on the ambient temperature control system 5. It can be designed in the gaps between the laid water channels 9 or installed in other locations; there are no restrictions. The number of heat exchangers 10 is also not limited, the same as the number of water channels 9, and is set according to the manufacturer's requirements or a preset number. The heat exchanger 10 can be made of metal, and its shape can be metal fins with a large heat exchange area, or metal plates with a smaller heat exchange area, or other materials and shapes; there are no specific restrictions. Its main function is to increase the contact area between the ambient temperature control system 5 and the ambient air. The ambient temperature control system 5 controls the ambient temperature by raising or lowering the temperature of the heat exchanger 10.

[0052] In addition to the above, the plant factory with this ambient temperature control system 5 should adopt a separate method for temperature and humidity control to avoid the problem of condensation on the surface of the LED lamp with this ambient temperature control system 5. Of course, the LED lamp with this ambient temperature control system 5 can also be set to control the temperature in the ambient temperature control system 5 to be higher than the dew point temperature during operation, thereby avoiding the condensation problem, but this will make the temperature control algorithm more complicated.

[0053] The provided LED lights with an ambient temperature control system can control the ambient temperature while controlling the LED light temperature, solving the problem that plant factories still need to add other equipment to control the ambient temperature, resulting in high investment costs.

[0054] Based on the above embodiments, this embodiment specifies that when it is necessary to lower the ambient temperature, the liquid temperature in the water channel must be lower than the ambient temperature, and when it is necessary to raise the ambient temperature, the liquid temperature in the water channel must be higher than the ambient temperature.

[0055] The liquid in the water channel can be tap water or other liquids, such as antifreeze; there are no restrictions. The water temperature in the water channel is controlled by a temperature control system located outdoors. When the indoor temperature is too high and needs to be lowered, the temperature control system controls the liquid temperature to be lower than the indoor ambient temperature, so that the liquid in the water channel can carry the heat from the indoor environment to the outside, thereby lowering the indoor temperature. When the indoor temperature is too low and needs to be raised, the temperature control system controls the liquid temperature to be higher than the indoor ambient temperature, so that the liquid in the water channel can heat the indoor air, thereby raising the indoor ambient temperature.

[0056] Ordinary liquid cooling modules can only remove heat from LED lights, without considering the ambient temperature. The water temperature can be higher or lower than the ambient temperature. However, this embodiment controls the liquid temperature in the water channel, thereby enabling the control of the indoor ambient temperature.

[0057] Based on the above embodiments, such as Figure 6 and Figure 7 The LED light module 6 shown has a temperature regulation system 20, which includes a water inlet 21, a water outlet 22 and a water channel 23; the temperature regulation system 20 and the ambient temperature regulation system 5 are independent of each other and the two systems are insulated from each other by heat conduction.

[0058] The inlet 21 and outlet 22 of the temperature control system 20 are similar to the inlet 7 and inlet 8 of the ambient temperature control system 5 mentioned in the above embodiments, and will not be described again here. The water channel 23 of the temperature control system 20, as shown in the figure, is a circular channel, but it can also be a square channel; this is not limited here. The temperature control system 20 can use a combination of ambient temperature water circulation and an outdoor water tower, or it can use other temperature control systems for water circulation to control the temperature of the LED light module 6.

[0059] By providing LED light modules with a separate temperature control system, the temperature control of the LED light modules is made independent of the ambient temperature control system, avoiding mutual interference between the two systems. The ambient temperature water circulation used in the above temperature control system, in conjunction with the outdoor water tower, saves energy.

[0060] Based on the above embodiments, considering that poor air circulation around plants can affect transpiration and thus plant health, this embodiment limits the following: Figure 8 and Figure 9 As shown, the LED lights in this ambient temperature control system also include a ventilation module, which includes an air inlet 11, an air outlet 12, and an air duct 13. The ventilation module is used to enhance air circulation around the plants and the heat exchange efficiency of the heat exchanger 10.

[0061] The ventilation module can be integrated with the heat exchanger 10 or installed separately. When installed separately, the air duct 13 is connected to the heat exchanger 10. When the ventilation module is installed with the heat exchanger 10, the air duct 13 can be installed on the heat exchanger 10. The air inlet 11 is connected to the air duct 13 and can be installed on the back of the LED light with the ambient temperature control system. The preferred installation position of the air outlet 12 is facing the top of the plant, that is, on the front of the LED light with the ambient temperature control system. Of course, it can also be installed in other directions of the plant. This is just a preferred installation position and does not constitute a limitation on the position of the air inlet 11 and the air outlet 12. The airflow enters the air duct 13 from the air inlet 11 and flows from the air duct 13 to the air outlet 12 and is discharged, which increases the air circulation at the top of the plant. When the air duct 13 is integrated with the heat exchanger 10, the air circulation in the air duct 13 also greatly enhances the heat exchange efficiency of the heat exchanger 10.

[0062] By setting up ventilation modules, air circulation around the plants is increased, avoiding interference with transpiration and ensuring plant health, while also improving the heat exchange efficiency of the heat exchanger.

[0063] Based on the above embodiments, this embodiment specifies that the LED lights in this ambient temperature control system, such as Figure 10 As shown, it also includes a heating module 14, which is used to heat the ambient temperature control system.

[0064] The heating module 14 can be an electrically powered heat-generating device, or it can generate heat using other methods. There are no limitations on its quantity or location. Figure 10 The proposed arrangement of the heating module 14 in the gap between the LED modules is merely one possible placement and does not constitute a limitation on its location. When the ambient temperature is low and the use of hot water in the temperature control system is insufficient to raise the heat exchanger temperature, the heating module 14 dissipates heat, thereby increasing the heat exchanger temperature and ultimately raising the indoor ambient temperature. This situation is generally unlikely, as the temperature control system can usually raise the ambient temperature quickly. Similarly, when the temperature control system is off and the indoor ambient temperature is too low, the heating module 14 also helps raise the indoor ambient temperature.

[0065] By setting up a heating module, the plant can be protected from frost damage caused by excessively low ambient temperatures, untimely temperature increases by the ambient temperature regulation system, or when the system is not functioning properly.

[0066] Based on the above embodiments, this embodiment further specifies that the LED lamp with an ambient temperature regulation system also includes: a temperature sensor and a temperature controller; the temperature sensor is connected to the temperature controller for collecting ambient temperature; the temperature controller is connected to the ambient temperature control system for controlling the ambient temperature control system and the heating module according to the ambient temperature and the on / off state of the LED lamp module.

[0067] The temperature sensor is used to acquire the ambient temperature and transmit it to the temperature controller. There are no restrictions on the model of the temperature sensor; it can be selected based on the manufacturer's requirements. Ideally, the temperature sensor should be set to acquire the ambient temperature in real time, allowing for more timely adjustments to the indoor temperature. One or multiple temperature sensors can be used. With a single sensor, its position can be in the center of the room for more accurate temperature readings. Using multiple temperature sensors allows for the acquisition of temperatures from multiple locations within the room, and the average temperature value can be calculated, resulting in a more accurate measurement compared to a single sensor. Alternatively, a separate temperature sensor can be installed on the LED light to monitor its temperature and prevent overheating, which could shorten its lifespan.

[0068] The temperature controller, in addition to connecting to the temperature sensor, also needs to connect to the ambient temperature control system and the heating module. Specifically, it controls the ambient temperature control system and the heating module based on the ambient temperature and the on / off status of the LED light module. As shown in Table 1, the operating modes of the LED light with the ambient temperature control system are as follows: When the ambient temperature is higher than the preset temperature (generally 25 degrees Celsius) and the LED light module is on, the ambient temperature control system is turned on. The water temperature in the ambient temperature control system must be lower than the preset temperature to remove heat from the room and achieve cooling. Simultaneously, the heating module is turned off. When the ambient temperature is lower than the preset temperature... When the LED light module is turned on, the ambient temperature control system is activated, with the water temperature above the preset temperature. The LED light module also generates heat during operation, thus raising the indoor temperature. Simultaneously, the heating module is turned off (though it can be activated under certain conditions). When the ambient temperature is above the preset temperature and the LED light module is off, the ambient temperature control system is activated, lowering the water temperature below the preset temperature, and the heating module is turned off. When the ambient temperature is below the preset temperature and the LED light module is off, the ambient temperature control system is turned off, and the heating module is activated to raise the indoor ambient temperature.

[0069] Table 1

[0070] Ambient temperature LED lighting module Ambient temperature control system Heating module greater than 25 degrees open Turn on (water temperature less than 25 degrees Celsius). close Less than 25 degrees open Turn on (water temperature greater than 25 degrees Celsius). close greater than 25 degrees close Turn on (water temperature less than 25 degrees Celsius). close Less than 25 degrees close close open

[0071] In the above embodiments, the position of the heating module is not limited. As a preferred embodiment, such as... Figure 10 As shown in the figure, this embodiment provides a preferred position for the heating module 14, which is placed in the interval between the LED strips of the LED light module 6.

[0072] At this time, the heating module 14 is set to be suitable for the length of the LED light module 6, and the width shall not be greater than the spacing width of the LED light strip; other aspects of the heating module 14 are as described above, and will not be repeated here.

[0073] By utilizing the gaps between LED strips in the LED module, the space utilization rate of this LED lamp with an ambient temperature control system is improved.

[0074] As a preferred embodiment, this embodiment is limited to, for example Figure 11 As shown, this LED lamp with an ambient temperature control system also includes a current controller 15 connected to the heating module and the LED lamp module; the current controller 15 includes a circuit including: a first power electronic switch Q1, a second power electronic switch Q2, a microcontroller U1, an amplifier circuit 16, and a driver.

[0075] The output of amplifier circuit 16 is connected to the input of driver to transmit a current control signal to driver; the control terminal of microcontroller U1 is connected to temperature controller, the first output of microcontroller U1 is connected to the input of amplifier circuit 16, the second output of microcontroller U1 is connected to the control terminal of first power electronic switch Q1, and the third output of microcontroller U1 is connected to the control terminal of second power electronic switch Q2, used to control the conduction of first power electronic switch Q1 and second power electronic switch Q2 according to the signal transmitted by temperature controller; the input of first power electronic switch Q1 is connected to LED lamp module, the input of second power electronic switch Q2 is connected to heating module, and the outputs of first power electronic switch Q1 and second power electronic switch Q2 are grounded to control LED lamp module or heating module; the output of driver is connected to LED lamp module and heating module respectively to control the current entering LED lamp module or heating module.

[0076] The first power electronic switch Q1 and the second power electronic switch Q2 can be either a field-effect transistor (MOSFET) or a semiconductor transistor. They can control their own conduction by controlling their control terminals, i.e., the gate of the MOSFET or the base of the semiconductor transistor. Moreover, not only power electronic switches can achieve the above functions, but relay devices can also be used to achieve the same functions.

[0077] The specific model of the microcontroller U1 is not limited, as long as it can achieve the above functions. The amplifier circuit 16 can be a non-inverting proportional operational circuit. Of course, other circuit structures of amplifier circuit 16 are also acceptable. The non-inverting proportional operational circuit can amplify the current signal while filtering out the common-mode factor in the current signal, thereby improving the accuracy of the current signal.

[0078] The driver can be an additional driver or the LED driver included in the LED light; anything that can achieve the above functions is acceptable. Using an additional driver will increase costs, while using the LED driver included in the LED light only requires connecting the heating module to the LED driver.

[0079] By setting a current controller, it is possible to control the operation of the LED light module and the heating module, and to control their working efficiency and the duration of their operation by controlling the current level of the LED light module and the heating module.

[0080] The above embodiments do not limit the first power electronic switch and the second power electronic switch. In this embodiment, it is limited to a MOSFET or a semiconductor transistor. The connection relationship between the first power electronic switch and the second power electronic switch will change accordingly in the above embodiments.

[0081] When the transistor is a field-effect transistor (FET), the control terminals of the first and second power electronic switches are the gates of the FET, the output terminals of the first and second power electronic switches are the sources of the FET, and the input terminals of the first and second power electronic switches are the drains of the FET.

[0082] When the transistor is a semiconductor transistor, the control terminals of the first and second power electronic switches are the base of the semiconductor transistor; the input terminals of the first and second power electronic switches are the collectors of the semiconductor transistor; and the output terminals of the first and second power electronic switches are the emitters of the semiconductor transistor.

[0083] Semiconductor transistors are commonly found in everyday life and are relatively inexpensive; MOSFETs are more expensive than semiconductor transistors, but they have advantages such as better radiation resistance and low noise, so manufacturers can choose according to their own needs.

[0084] In this embodiment, the heat exchanger is limited to a metal plate; the metal plate is made of a metal with good thermal conductivity, such as aluminum, copper, or aluminum alloy.

[0085] Metal flat plates have a relatively simple structure and low cost.

[0086] In this embodiment, the heat exchanger is limited to metal fins, and the material of the metal fins is as follows: metals with good thermal conductivity, such as aluminum and copper.

[0087] Metal fins have a complex structure and are more expensive, but their area is larger than that of metal plates, thus making heat exchange more efficient.

[0088] This application also provides an example of an application scenario for an LED light with an ambient temperature control system in a plant factory, such as... Figure 12 and Figure 13 As shown, an application scenario diagram of an LED light 17 with an ambient temperature regulation system installed on a plant shelf 18 is given. The plant shelf 18 is divided into 4 layers, each layer is approximately 0.6m high (H), and each layer holds 8 LED lights 17 with an ambient temperature regulation system. The total length (L) is approximately 9.5m and the width (N) is approximately 1.1m. Each shelf will have 32 LED lights 17 with an ambient temperature regulation system, and the area of ​​each LED light 17 with an ambient temperature regulation system is approximately 1.2 square meters. Figure 14 A top view is given of the above-mentioned plant stand equipped with LED lights 17 having an ambient temperature control system in a 100-square-meter plant factory, wherein in this plant factory, plants are arranged as follows: Figure 12 The provided plant rack 18 can accommodate 5 plants, with an aisle 19 approximately 1m wide between each rack. It uses 160 LED lights 17 with an ambient temperature control system. Because each light has two sides, the effective heat exchange area is approximately 384 square meters, far exceeding the area of ​​currently used liquid-cooled floors, thus significantly enhancing its temperature regulation capabilities. Furthermore, as... Figure 12 As shown, each LED light with an ambient temperature control system corresponds to a plant below it, creating a "microclimate" around the plant. This avoids the problem of low temperatures around the plant stand but high temperatures at the top of the plants, which is common with centralized air conditioning. Moreover, this "microclimate" is the same for every plant, reducing temperature unevenness. Furthermore, if the LED lights with ambient temperature control systems have ventilation modules, it further promotes the downward flow of cool air to the top of the plants, strengthening the "microclimate" and further benefiting plant growth and energy conservation.

[0089] This embodiment provides an application scenario of the LED light with an ambient temperature control system in a plant factory, which has the same beneficial effects as the LED light with an ambient temperature control system described above.
